Some of our patients’ most
frequently asked questions
regarding cardiovascular
diseases are listed below:
Is there a difference
between arteriosclerosis and
atherosclerosis?
Yes, there is a difference.
These are two different
diseases:
Arteriosclerosis (generally)
encompasses a group of
diseases with one common
characteristic: The loss of
elastic fibres in the wall
of the blood vessels, and
their compensation with
connective tissue fibres.
Because of this arteries
become stiff and
non-elastic. Basically,
arteriosclerosis is one of
multiple manifestations of
the body growing old.
-
Atherosclerosis is one
form of
arteriosclerosis. This
process is characterised
by the forming of
limited plaques
(atheroms) in the blood
vessels wall. These
formations consist of
fat (lipids), connective
tissue and calcium.
Growth of these plaques
is fast and progressive,
and they obstruct the
blood vessels lumen in
limited length and in
that way cause
deregulation of blood
flow and nutrition of
organs and tissue.
Results depend on which
arteries are affected.
-
Atherosclerosis of
coronary arteries is
cause of coronary
disease
-
Atherosclerosis of brain
arteries cause
cerebrovascular disease
with brain attack
(stroke) and others
complications
-
Atherosclerosis of
arteries in legs cause
ischemic disease of
lower limbs that can
result in gangrene and
loss of limbs
What is coronary
atherosclerosis?
Coronary atherosclerosis is
a process of plaque forming,
atherom, in coronary
arteries. They start to form
after twenty years of age
and within the next decade
almost nobody is spared of
stiff plaques in coronary
arteries. The disorder is
caused by insufficient blood
flow to heart muscle and
starts when lumen of one of
three big coronary arteries
is obstructed more that 50%.
Then symptoms, well known as
coronary disease, start to
show.
What is coronary
atherosclerosis?
Coronary disease (coronary
heart disease, ischemic
heart disease) is a group of
symptoms and disorders
caused by coronary
atherosclerosis, and
disorders relating to the
transport of oxygen and
other substances in the
blood. It’s not a singular
disorder. It can be found in
five forms that can
transform one to another.
-
Angina pectoris, chronic
coronary insufficiency
or stabile form of
angina pectoris is a
state caused by
atherosclerosis of
coronary arteries and
insufficient oxygen
supply to the heart
muscle, in cases of
increase need for it.
The main sign of disease
is chest pain during the
physical extortion, in
stress, after large meal
and after prompt
temperature changes.
Angina pectoris is not a
stable disease, it
progresses during the
time and develops into
much serious
condition.
-
Unstable angina pectoris
is more progressed
condition with faster
and more progressive
atherosclerosis in one
of bigger coronary
arteries. There is also
chest pain, but it is
stronger and it can show
in passive state, with
out extern factor
provocation. If disease
development is not
stopped, 40% of patients
will have infarct of
heart muscle in less
that a three months, and
30% more in the next six
months.
-
Infarct myocardium is a
condition of partial
heart muscle necrosis
(tissue dying). It is
caused by complete blood
flow in one of coronary
arteries and stop of
oxygen transport to
myocardium. Most
commonly it starts when
thrombi (blood clot) is
formed in blood vessels
in place where plaque is
already exists in the
wall, and this lead to
complete obstruction.
Is there a certain warning
sign that heart attack is
about to happen?
Only in patients with
previous angina pectoris. In
this group of patients,
heart attacks are becoming
more frequent and can be
stopped with medications.
But, it goes only for one
third of infarct victims. In
most cases infarct is not
announced by chest pain or
choking/hard breathing. It
comes slowly and occurs
unexpectedly in the
patients’ life "like thunder
in clear sky”.
Does one know when a heart
attack occurs?
It’s not that simple.
Typical pain doesn’t occur
in the left side of the
chest, but patient feels
tight feeling, burnings and
pressure. Sometimes this
feeling doesn’t go down the
left and right arm or the
patient just sweats
profusely and can end up
having pain in the back or
even in the abdomen.
If the patient feels heart
pain more than for half of
an hour, with out any
hesitation should call ER!
Not a second should be lost,
because in that case the
only medication is- away to
hospital.
Can one survive a heart
attack without feeling it?
It is possible. That heart
attack is called silent and
usually is small and of
weakest nature.
Are there more and less
dangerous types of heart
attack?
Yes. It depends on how much
time the heart muscle tissue
was left without oxygen and
how much of it died. Front
wall heart attacks are much
more dangerous than rear
wall and young people cope
less than the elderly.
How quickly should
assistance be given in a
case of heart attack?
Nowadays up to six hours
after the obstruction of
blood vessels occurred,
using medication, the blood
clot can be dissolved. This
intervention is 100%
successful. If this
treatment is applied later
it will be less successful.
Is heart attack hereditary?
Heart attacks in themselves
are not hereditary, but
being genetically prone to
them is. For example, if
parents and grandparents
have had or have died from
heart and blood vessels
disease, the children should
lead a healthy way of life.
Can cholesterol obstruct
blood vessels that feed the
heart?
No. Modern medicine has
found a lot of causes of
blood vessel obstruction.
Still, it is not believed
that high blood cholesterol
levels can cause it. The
cause of obstruction is an
increasing number of cells
in blood vessel wall and its
inner layer. These cells are
projected into the arterial
interior and can multiply.
Then its thin inner layer
can easily burst causing a
mini bleeding that the body
tries to heal. The blood
vessel then shrinks to stop
the formation of a small
wound. But the blood vessel
is further obstructed that
way and can be completely
blocked by thrombocytes.
Later on cholesterol
particles can accumulate on
the surface of these
narrowings. The first phase
involves the growth of cells
rather than cholesterol.
Can anything be done to stop
the growth of these cells?
Unfortunately, no. To this
day this is still understood
as a matter of fate. The
solution could be traced to
the field of gene therapy,
but this is still only a
possibility in the future.
What are the signs and
symptoms of acute heart
attack?
The decrease of blood starts
to manifest strongly in the
moment when the heart as a
muscle pump is under greater
demand (increased heart
rate, higher blood pressure,
extortion, increased body
temperature) when heart
muscle have higher demand
for oxygen. This oxygen
insufficiency in certain
number of patients is
manifested as a pain-angina
pain. This pain is the heart
muscle alarm saying that it
needs oxygen, that’s why
angina pain is called “heart
muscle scream for oxygen”.
Unfortunately, numerous
patients don’t have anginas’
pain, in this cases it is a
silent ischemia.
Sudden heart dead is the
biggest problem is modern
cardiology, because patients
get heart attack suddenly,
with out any warning sings.
This group of patients, in
case of heart attack, can be
helped only if someone is
near by to start prompt
heart massage and “mouth to
mouth” respiration at the
place of the accident
because brain cells can’t
sustain more than 3-5
minutes without oxygen and
in this short period it is
unlikely that ER can come.
It’s important to recognise
acute heart attack, call ER
and in the meantime start
resuscitate till paramedics
arrive.
These are the reason why we
give you symptoms and signs
of acute heart attack:
-
Feeling of strong
tightening or pressure
on chest
-
Sudden loss of air
-
Unbearable chest pain
that last for some time
-
Pain that started in
neck and spreads to jaw
and left hand
-
Any chest pain that last
more that 20 minutes
-
Pale, cold, sticky-wet
skin
-
Nausea and vomiting,
from mild to strong
-
Vertigo, instability and
impossibility to get up
-
Irregular heart
activity
-
Loss of heart
activity-no pulls
A person who identifies any
of the above symptoms should
be transferred to medical
facility, preferable the one
with intensive care unite,
and even more coronary
intensive care unites. |
